Question
Which of the following compound reacts in water only?
- Oxalic acid crystals
- Ammonia
- Silver nitrate
- Sodium chloride
Hint:
Oxalic acid crystals reacts only in water
The correct answer is: Oxalic acid crystals
Oxalic anhydride recrystallized in the presence of water was identified as α form. The deuterium exchange reaction between oxalic anhydride and water of hydration takes place in oxalic anhydride partially hydrated with heavy steam. This exchange rate is virtually independent of temperature.
